SCHLAGE ND-Series Electrified Locks Instructions

ND-Series Electrified Lock

For standard installation, see full instruction sheet.

Select the appropriate mode for the installation using the mode select switch located on the chassis. Note: When mode is switched (from EL to EU or EU to EL) the lock requires a complete lock/unlock power cycle to synchronize to the proper mode.

EL, electrically locked (fail safe):Outside knob/lever or both outside and inside knobs/levers (depending on function) will lock when power is applied. In the event of power failure, the opening will be unlocked.

EU, electrically unlocked (fail secure):Outside knob/lever or both outside and inside knobs/levers (depending on function) will unlock when power is applied. In the event of power failure, the opening will be locked.

Electrical requirements:

The ND-Series electrified locks are powered by DC power only. DO NOT USE AC POWER.

Voltage: 12 or 24 V DC (maximum 26.4 V, minimum 10.8 V)
Holding current: 10 mA
Peak current: 230 mA
Operating temperature: 32°F to 120°F (0°C to 49°C)
All power requirements shown are for single lock operation.

AWG	14	16	18	20
Voltage	12 V	500’ (152 m)	300’ (91 m)	200’ (61 m)	100’ (30 m)
24 V	Up to 1000’ (304 m)

Note: Either lock wire may be attached to either power supply terminal (+ or -).

Troubleshooting:

If lock does not operate –

Ensure the lock is powered with DC power.
Ensure the input voltage is between 10.8 and 26.4 volts DC.
Do not use AC power

Request-to-Exit (RX) Lock

RX utilizes a microswitch inside the lock case to detect rotation of the inside knob/lever. The switch then signals the use of the opening to the security system.Attach wires from RX switch wire harness to an electrified hinge/EPT (not furnished). Refer to the Allegion Connect section below for wire identification. Electrical rating: 2 A, 30 V DC

RX Switch kit #N123-062 installation:Attach switch assembly to pin on chassis using the screw (included with kit).Use RX anti-rotation plate (see inset).

Allegion Connect

Allegion Connect, a factory-installed Molex® connector system, provides simplified installation and maintenance utilizing quick-connect harnesses and hinges. Alternatively, the Molex connector may be cut off and the lock installed with traditional wire splicing methods.
